Eve Arden stars as the tart-tongued Constance Brooks, a dedicated English teacher at Madison High School. Before and after the bell rings, Miss Brooks turns her thoughts from language to love. Indulging in her perpetual pursuit of bashful biology teacher Philip Boynton (Jeff Chandler), Connie finds herself making his favorite stew, conspiring to make him sick, and pretending to be his mother! She even considers compromising her principles (and her principal)!

Miss Brooks has a rival for the attentions of that handsome specimen: Miss Daisy Enright (Mary Jane Croft). She's a good cook, a master of the thinly-veiled insult, and every bit as competent and ruthless as Connie!
